As free camping is something that we have always enjoyed, l jumped on a couple of huge 250 watt solar panels l stumbled across at a local recycling place recently. They were only asking $50 each so after ringing a local business about how to test that they even worked, l brought 2 of them. They were obviously from a house roof or similar going from the size of them on the back panel says that they are good for about 37 volts each, which a multi meter agrees with. Dickhead me thought I was onto an absolute bargain until l rang a solar panel installer who informed me that l would need a solar regulator or controller to avoid overcharging my batteries. He told me which one to get and l almost died when I found out it was going to cost another $250- $300 to get it sorted out. Next time I will do more research before impulse buying.

I am no expert but if they came off a house then they will be 24 volt panels.

To use them for camping all you need is to connect them to an MPPT Solar Controller that converts 24 to 12 volts.
